WINDMILL.

Application led December 8, 1921. Serial No. 520,853. v

To all whom t may concern Be it known that l, ANTONI BRZYKGY, a`

citizen of the United States. lresiding at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in "Windmills; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others` skilled in the art -to which it appertains to make and usethe same.

My present invention relates to windmills, and more particularly, to power transmission mechanism therefor.

Such transmission mechanism which includes an upright shaft connected, by gears, to the wind wheel shaft and lhaving its exisat the axis of the rotary head on which the wind wheel shaft is journaled, is objectionable for the kreason that the driving torque transmitted through the upright tends to rotate the head in the direction of the rotation of the upright shaft, and, hence, tends to move the wind wheel out of the wind. l The object vof my invention is to eliminate this objection by providing a transmission mechanism having a belt drive. n

Tb the above end, generally stated, the invention consists of the novel devices and combinations of devices, hereinafter described and'defined in the claims.

ln the accompanying drawings which illustrate the invention, like characters in dicate- -like parts vthroughout the several views. "Referring to the drawings Fig. 1 is a view principallyin elevation with some parts sectioned. showing a windmill 'having one lform of -the invention embodied therein; y

Fig. 2 is a view partly in plan and partly in horizontal section, taken on the line 2 2 of Fig. 1; v

Fig. 3 yis a fragmentary View, partly in plan and partly in section, taken on the line 3 3 of Fig. 1;

Fig. v4 is a fragmentary detail view. partly in elevation and partly in central vertical section;

Fig. 5 is a fragmentary detail view with some parts sectioned on the line 5 5 of Fig. 4;

Fig. 6 is a view corresponding to Fig. 4, but showing another form of the invention;

7 is a detail view with some parts sectioned on the line 7 7 of Fig. 6.y

Referring first to the invention shown i in Figs. 1 to 5 inclusive, the numeral' 8 indicates a windmill tower lof the usual construction andk has, at its top, a turntable 9.' A platform 10. and a cross timber 11 are securedto the tower 8 below theturntable 9, 'and the latter 'below the former. A vane 12 is carried by the shank 13 having, at its inner end, a large hub 14 supported onanti-friction devices 15 from the turntable 9. I

On the under `side ofthe head 16'is a bearing sleeve 17 rotatably mounted on the y desired construction, is keyed to one end` of a horizontal shaft21 journaled in a pair of aligned bearings 22 formed with lthe bracket 19 and located on diametrically opposite sides of the shaft 18. Axially aligned Y with the shaft 18 and endwise spaced therebelow, is a shaft 28', the upper end of which is jour-naled in a bearing block 24 and the lower end of which is journaled in a bearing 25 inthe cross timber 11. The bearing block 24 is rigidly secured to the shaft 18 forrotation therewith, by a pair of depending bars 26, the upper ends of which are bolted f to the outer sides of the lower end'portion ofthe shaft 18 at diametrically opposite points and the lower ends of said bars are bolted tothe bearing block 24 which extends therebetween.

The shaft 28-is driven from the wind wheel shaft l21 by a belt drive which comprises an upper section 27v and a llower section 28, bothof which are in the form of chains.` The upper section 27 of the belt driveiis arranged to run over a chain wheel 29 on the shaft 21 and a chain wheel 30 on a short shaft 31 journaled in the bars 26. The lower belt section 28 is arranged to run over a chain wheel 32 onthe shaft 31 outward of the bars 26 and a chain wheel 33 on the upper end of the shaft 23. The lowerv section 28 of the belt ydrive also runs over rotatable head, of a wind wheel having a shaft journaled on the head, a tubular shaft secured for rotation with the head7 a bearing head carried by the tubular shaft, a driving shaft journaled on the bearing block, wheels on the wind wheel shaft and the driving shaft, a pair of connected wheels journaled on the tubular shaft, a belt drive comprising upper and lower sections, said upper section being arranged to run over one of said connected wheels and the wheel on the wind wheel shaft and said lower section being arranged to run over 'the other of said connected wheels and the wheel on the driving shaft, and guide sheaves journaled on the bearing block for changing the direction of travel of the lower section of thebelt drive.

T. In a windmill, the combination with a rotatable head, of a wind wheel having a shaft journaled on the head, an upright tubular shaft secured at its upper end to the head for rotation therewith, a pair of deblock secured to and between the lower ends of said bars, a driving shaft axially aligned with the tubular shaft and journaled inthe bearing block, wheels on the wind wheel shaft and the driving shaft, a pair of connected wheels journaled on said bars, a belt drive comprising upper and lower sections, said upper section being arranged to run over one of said connected wheels and the wheel on the wind wheel shaft and said lower Section being arranged to run over the other of said connected wheels and the wheel on the driving shaft, and guide sheaves journaled on the bearing block for Changing the direction of travel of the lower section of the belt drive.

In testimony whereof I alix my signature.

ANTONI BRZYKCY.
